Lunar IPS (LIPS) is intended as an easy to use, lightweight IPS patch utility for windows to replace the SNESTool DOS program. It can both create and apply IPS patches.
What's New in Version 1.01
IPS patch creation/application support.
full RLE encoding/decoding support.
file expanding/truncating support.
the IPS encoder creates files that are the same size or smaller than files created with SNESTool.
the IPS encoder avoids the rare "0x454F46 (EOF) offset bug" that SNESTool's IPS encoder has.
logging feature for applying IPS patches (ROMFileName.log).
registers the ".IPS" file type so that you can just double click on an IPS file and choose the file to apply it to for convenience.
support for patching files up to 16 MB in size, which is the limit of the IPS format. The files can technically be larger than that, but the IPS format cannot record changes beyond the 16 MB mark due to 24-bit addressing. The IPS file itself can be any size.
